| Popis: | The dummy load is an essential part of Loran transmitter whose role is paramount in local positioning applications. The duty of the dummy load is to provide the equivalent impedance of the antenna to connect to the Loran transmitter when the antenna is disconnected. For the realization of the dummy load with specified impedance values, the inductance of the self-loading section is designed precisely. In this regard, this paper deals with inductance matrix and equivalent inductance calculations, corresponding to stranded and solid cables. Inductance matrix components, consisting of mutual and self-inductance, are calculated analytically and then are validated by the finite element method (FEM). The divergence of analytical calculations from FEM results is investigated as coil pitch changes. In addition to inductance, parasitic capacitances will be taken into consideration to determine the equivalent circuit of Loran transmitter inductor. With regard to the calculated inductance matrix and parasitic capacitances, the ladder equivalent circuit of the inductor will be presented. |
